To all whom t may conce/m:

Be it known that I, HERBERT CHAMPION HAiniIsoN, a subject of the King of Great Britain, residing at Lockport, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Radiator Units; and I do hereby declare the following to be a' full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to automobile radiator units and especially to the division plates separating each pair of outerwalls or plates forming said unit in an automobile radiator, and has for its object to render said radiator units more efficient in extracting heat from the water traversing the water passages with which said units are asso' ciated than has been the case heretofore..

It is well known that when air is forced through a passage with a view to extracting heat from the walls of said passage, the more intimate each particle of air is made to contact with said walls, the more efliciently will the heat be extracted. Therefore. according to this invention the air passing through the cells of the radiator is thoroughly broken up and efiiciently thrown against and made to contact with the hot outer walls of said cells, all as will appear below.

IVith these and other objects in view the invention consists in the novel details of construction and Combinations of parts more full;7 hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the Figure 1 is a plan view of a partition plate for radiator units made in accordance with this invention; g

Fig. 2 is an edge view of the parts shown in Fig. 1;

Figs. 3, 4. 5 and 6 are sectional views taken respectively on the lines 3-3, 4 4, and 6%6 of Fig. l, looking i'n the direction of the arrows;

Fig. 7 is a sectional view, taken on the line -T of Fig. 8, showing a radiator unit provided with the division plate illustrated in Fig. 2 and a. pair of water passages: and

Fig. 8 is a sectional view taken On the line `face`s 2G and 27.

van adjacent unit provided with the fiat cell walls or plaits 3. rI'hel unit 4plate 1 at its edges is provided with the offsets 4, and the unit plate 2 is provided at its edges with the offsets 5*, which meet in the planes 6 to form the water passages 8, (see Fig. 7 In like manner the unit plate 9 is provided with the offsets 10, and the unit plate 11 is provided with'the offsets 12 whiclrmeet in the planes 13 to form the water passage 14. The plate `11 is also provided with the fiat celll walls or plaits 16, extending in a direction opposite to that of the flat walls or plaits 3, and preferably staggered or alternating with said walls 3 as shown. Between the oppositely extending plaits 3 and 16 is located the diviA sion platey 18- preferably corrugated as shown, and provided on one side with guiding and centering projections 20. Each projection 2O is provided with an inclined guiding surface. 21 extending in one direction, and -with an' inclined guiding surface .22 extending in an opposite direction, and

the said surfaces 21 and 22 of adjacent projections meet in the centering grooves or depressions 23 as shown.l

In the same 'way the other side of said division plate 18 is provided with guiding and centering projections 25, each -having oppositely extending inclined guiding sur- Said surfaces 2G and 27 of' adjacent projections 25 likewise `meet to form the centering grooves or depresions 28 askillustrated. It will be clear from the drawings that each of the centering grooves 23 and 28 are .located on abend or ridge such as 30 forming a corrugation in the plate 18.

It will be further observed that the oppositely inclined sides 3,2 and 33 of the corrugated plate 18 extend throughout the width of said plate 18 while the oppositely extending projections 20 and 25 are located in rows, and only extend over a portion of vthe width of said plate 18. It will also be CORPORATION OE NEW Aha third air deflecting surface 35 or 36; In other'w'ords, each .projection 20` or 25. as will be clear from the-,drawings 1s formed by perforatinw and forcing up the metal- I from the bottom of a corrugated anglefsuch as 30, and it constitutes a sort ofhood to catch any air that ymay traverse said angle or depression 30. It thus forces said air to pass from one side to the other of the plate .18. Stated in other language, if we suppose inFig. y6 thataplait 3 is located on a corrugated angle 30, and occupies the centerving depressions 23, the position of the parts will be that illustrated in the upper half of Fig. 7. If we now imagine in Fig. 6 that an oppositely projecting plait 16 contacts with the opposite and adjacent corrugation 30 on the other side -of the plate'18, and in .such 'a manner as to occupy the centering depressions 28 formed bythe guiding surfaces 26 and 27 of adjacent projections 25, then the parts will occupy the position shown in the lower half of Fig. 7.

To make the construction more clear it is said :-An end view of the division plate 18 such as appears inFig. 2, does not showI the air deflecting surfaces 35 of said projections 20, but shows instead the opposite deflecting surfaces 40 of said projections 20. In the same way the outer surfaces 36 of the projections 25 do not appear in said Fig. 2, but their other sides 42 do appear therein.

These said deflecting surfaces 40 and 42v Fig. 7), that water passages such 'as 8 and 14 are located on the outside of eachnnit, and that the said separating or division plate 18 is provided with oppositely extending projections such as 20 and 25, each having guiding surfaces su'ch as 21 and 22, and 26 and 27 respectively, which surfaces are adapted to guide the plaits such as 3 and 16 into the centering depressions such as 23 and 28, when the parts are assembled.

It will furtherbe clear that these said projections 20 and125 ldo not extend from edge to edge of the'division plate 18 as do the corrugated r angular portions such as 30, but that the said projections, on the contrary, extend in rowsfrom end to end of the division plate 18 and only occupy a comparatively small portion of its width. It will still further be"observed that each projection, such for example as 20, is provided with a deflecting surface such as 35 which serves to deflect any air which may flow along a corrugation such as 30 and that thel opposite side of the projection 20 is provided with a similar. deflecting surface such as 40, which will deflect any air which may flow along the opposite side of the plate 18 or along a companion corrugation 30 of said plate 18. Stated in other-language, no matter which way the air may traverse the width offthe plate 18, it will be deflected toward a unit plate 2l or toward a unit plate 11, bya surface such as 35er 40 as the case may be. rIn the same way, it will be observed that air traversing in either direc- ,.tion the width of the unit plate 18 will -.be likewise deflected toward the outer unit plates 2 and 11 by-the surfaces such as 36 and 42, that are associatedwith the projections 25. v

As a matter of fact, supposing the air to be traversing the cells of the radiator from right to left, as seen in Fig. 8, and as is indicated by the arrows in said ligure, it is evident that the delecting surfaces 42 associated with the projections 25 will deflect the air toward the unit plate 2, while the surfaces 40 associated withthe projections 2O will deflect said air toward the unit plate.

11, and further, 'sincesaid surfaces 40 and 42 alternate with respect to each other, the said l,air will be balloted to a greater or less extent backward and forward between the said unit plates 2 and 11, and thus it will be broken up and brought into a most intimate contact with said outer unit plates 2 and 11, and therefore most eiiiciently extract heat .from the water passages 8 and 14. In thel drawings there is illustrated two pairs of rows of projections 20, and two rows of projections 25, but it is evident that these projections may be increased or decreased according to the desire of the manufacturer. The projections in each row are further staggered with relation to each other, but it is evident theymay be placed in any .other suitable relation.

It 1s an important feature of this invention. that although the air is thus broken up and balloted backward and forward between the outer unit plates 2 and 11, yet the projections 20 and 25 are so located that they still provide the guiding surfaces such as 21 and 22 and such as 26 and 27. These said surfaces serve to automatically center the plaits such as 3 and 16 during the assemblage of the parts, as will be clear from my Patent #1,169,481, dated J an. 25, 1916, and entitled Process of making automobile radiator sections. l

By employing the construction above disclosed I am not only enabled to retain the advantageous features described in my said patent, but I amalso enabled to thoroughly breakup the air passing through the radiator cells and to therefore extract more heat from the water. passages 8 and '14 than would otherwise be possible.

It is obvious that the division plate 18 .may be provided lwith perforations, guiding and centering projections as well as air deflecting surfaces disposed in other relations to each other than those disclosed without departing from the spirit of the invention and therefore I do not wish to be limited to the above disclosure except as may be required by the claims.
